1. Is there a way to browse the list archives, as opposed to search?
You can more or less browse the archives by date

2. I'm trying to distort an image and when the distort filter nears
the edge of the image (or sprite) the image actually scales and/or
moves. How do you stop this from happening?
Mouse over the output Image port of the Bump Distortion. You'll
notice that the image is getting larger as the black appears on the
side.
You'll need to crop the image to the original size (use the Image
Dimensions patch) to prevent this.
3. Are units in pixels? And if you have a 400x400 billboard and then
scale it to .5 is the center still 200,200?, or does it depend how you
have your patches nested?
Quartz Composer Units are different from pixels. You can read more
about the QC Coordinate system under Quartz Composer Basic Concepts ->
The Coordinate System

The reason QC uses this coordinate system instead of pixels is b/c QC
is designed to target arbitrary display devices of differing sizes/
aspect ratios.
Let me know if this doesn't make sense.
As for Core Image, there is a rather abstract description of the CI
Coordinate system in this document under Core Image Concepts ->
Working Space.

The coordinate system is centered at the lower left hand corner of
your image and is expressed in Pixels.
